Testing using browser

Visiting https://ok.local:8000 surely triggers: "This connection is not private" for Safari and NET::ERR_CERT_INVALID for Chrome.

For Safari you can force to visit the website. While in Chrome you can type the magic word: badidea or thisisunsafe in the page.

Tips

Add ok.local entry in your /etc/hosts.
